Other/modes of applying the principle of my invention may be employedinstead of the one explained, change being made as regards the mechanismherein disclosed, ro-

i ided the means stated by any of the fol owing claims or the equivalentof such stated means be employed.

I, therefore, particularly point out and distinctly claim as myinvention:

1. 111 a carbureter', the combination of a casing constituting a mixingchamber, a plurality of radial fuel nozzles therein, a ring valvedisposed between the wall of said casing and said nozzles and partiallyclosing the passage therebetween, a valve normally closing said nozzlesand connected to said rin valve to operate in unison therewith, an aflange on said ring valve on the side adjacent to said nozzles, saidflange bein adapted to delay the full opening of sa'i nozzles.

2. In a carbureter, the combination of a casing constituting a mixingchamber, a plurality of radial fuel nozzles therein, a ring valvedisposed between the wall of said casing and said nozzles and partiallyclosing the passage ther'ebetween, a valve normally closing said nozzlesand connected to said rin valve to operate in unison therewith an adepending flange on said ring valve on the side adjacent tosaid nozzles,said flange being adapted to delay the full opening of said nozzles.
